| Abstract: | The basic mechanical properties of low-intensity self-compacting concrete are systematically studied.The correlativity among the axial compressive strength,splitting tensile strength and elastic modulus of low-intensity self-compacting concrete and cube compressive strength of low-intensity self-compacting concrete are analyzed through the least square method.The experimental results show,with the same strength of ordinary concrete contrast,the axial compressive strength,splitting tensile strength and elast... |
